I mean there are many different political movements working within the EU so that might be part of it.

It's very very clear that many politicians are rather clueless on how ChatControl would actually work. The EU Commission wrote on their mastodon that they would only be scanning messages with CSAM, and that they wouldn't scan other messages... Which of course isn't possible because you need to scan the message in the first place to figure out which contain CSAM and which do not.

Some of the politicians are also clearly just interested in the direct violation of people's privacy. Peter Hummelgaard directly said "We must break with the totally erroneous perception that it is everyone's civil liberty to communicate on encrypted messaging services"... So he clearly doesn't care about the right to privacy...

Other politicians seems to be completely dazzled with the spiel about "it's for the children" and doesn't care what liberties are lost in the process of saving the children.
